Lauren Conrad Is Engaged (Ring Photo!)

The Hills star, blogger and fashion designer Lauren Conrad announced her engagement to USC law student William Tell this weekend and showed off a stunning round cut diamond solitaire ring. We're also loving the beauty blogger's classic red manicure that she rocked for the ring reveal. Ever since her debut on Laguna Beach, Lauren has been one of our favorite icons for fashion and beauty, not to mention ponytail inspiration, so we're expecting her wedding to be the definition of chic and effortless SoCal style.
